Trait StateReader 

pub trait StateReader: Send {
    type Receipt: Send + Sync;

    // Required method
    fn get_state(
        &self,
        block: BlockNumber,
    ) -> ProviderResult<Option<ExecutionOutcome<Self::Receipt>>>;
}

This just receives state, or [ExecutionOutcome], from the provider

Required Associated Types

type Receipt: Send + Sync

Receipt type in [ExecutionOutcome].

Required Methods

fn get_state( &self, block: BlockNumber, ) -> ProviderResult<Option<ExecutionOutcome<Self::Receipt>>>

Get the [ExecutionOutcome] for the given block
